Nitric oxide (NO) is produced by solar photolysis and auroral activity in the upper mesosphere and lower thermosphere region and can, via transport processes, eventually impact the ozone layer in the stratosphere. This work uses measurements of NO

Artemia salina (brine shrimp) has been successfully used for toxicity testing, and a screening test for phototoxicity has been developed based on this method. The ability of the method to test the phototoxic potential of seven known compounds was inv

The enzymatic hydrolysis and biological activity of a series of retinoates, esters of all-trans retinoic acid, were studied. Hydrolysis was conducted in pig liver esterase in aqueous solution. Toxicity was measured by brine shrimp (Artemia salina) bi

A strain of the cyanobacterium Oscillatoria agardhii non-toxic to mice was toxic to the crustaceans Daphnia pulex and Artemia saliva. The 48 h EC 50 -value of a water extract to D. pulex corresponded to 0.26 mp/ml of freeze-dried cyanobacteria, and t
